• Visual C++ Is the C-library heap checking on?

  Hi, I am compiling a C-program in VS2003, and started wondering, is the C-library's heap checking on, if I compile with _DEBUG, but use Multi-threaded DLL (/MD) runtime library and link with non-debug version of the C-libraries Hi, thanks for answer. I don't use the MT switch since it causes trouble with a DLL the program is using. Haven't had problems with this scenario, was just bit worried about mixing _DEBUG preprocessor directive and non-debug C-libraries. ...Show All

• .NET Development Changes made to SQL Server Express do not persist outside of debug run of application

  Hi, I am a complete newbie to C# programming and I am playing with reading/writing to/from a SQL Server Express database using Visual C# 2005 Express. I am actually following along with one of Bob Tabor's excellent tutorials from the Microsoft Visual C# Express Beb Site - Tutorial #9 - Databinding. My problem is that altough I can make updates to the SQL Server database which are immediately reflected if I then browse the data, these changes do not persist when the application terminates. I have compared my code to the example project code, and everything looks identical - but whereas updates made to the SQL Server Express database by the example code persist outside of the application run, updates made by my code do not. I have f ...Show All

• .NET Development Network Logon Failed-Home network

  I am testing a simple remoting solution and it works fine with all of the components on the same computer. However, when I test over 2 machines on my home network I am able to connect to the remote machine (and instantiate the remote object) with no problems, but when I attempt to call one of the remote object's methods I get a System.Security.Authentication.AuthenticationException exception: "A remote side security requirement was not fulfilled during authentication. Try increasing the ProtectionLevel and/or ImpersonationLevel." with an inner exception of: "The network logon failed" I am guessing that this is similar to connecting to SQL Server over a home network where you can't use Windows Authentication across ma ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Calling Present() with sync interval of 1 in windowed mode

  Hi all, I'm currently working on porting an existing engine to D3D10 (using Vista RC1 build 5600, DX9 SDK Aug 2006) on RefRast. With a windowed device I get the following debug output when calling Present(1, 0) on my swap chain. First-chance exception at 0x7676dde0 in ArtPreviewerDebug.exe: Microsoft C++ exception: _com_error @ 0x0012f458. If I call Present(0,0), i.e. with no wait for sync interval I don't get the error. Is this simply a change for D3D10 that you can't wait for the vertical sync in windowed mode any more or is there some other issue I'm missing I get the same results if I modify one of the D3D10 samples to call Present(1,0). However, when I try to switch one of the D3D10 samples to fullscreen to see if I can confirm my th ...Show All

• SQL Server Transferring data from read-only source to destination.

  Hi, I have read only permission in the source (OLTP) database. The source database is running in SQL Server 2000 and the size is more than 200 GB. I need to pull data from source and load target which is running in SQL server 2005. Following are the objectives I want to achieve. Data should be loaded on incremental basis. Whatever changes take place (Update/Delete) in source, that should be replicated to already uploaded data. Here I want to mention that, the source database does not have any identification key or timestamp column like Updated_Date by which I can filter the data which are recently inserted or updated into the source and upload the same. The source does not maintain any history data also. So I do not h ...Show All

• Windows Forms Newbie question: Controlling the styles of fonts etc. in an application

  I would like to use some teqnique to control e.g. the fontstyle for labels and textboxes in a WinForms application (.Net 2.0). I am looking for something similar to stylesheets or masterpages . What is the easiest way to do that I have tried one approach, but I cannnot get it to work the way I want it. I have made subclasses of the controls I would like to be able to set the style for. But when I assign a value for a property in the constructor of the class. The GUI builder also assigns (hardcode) that value in the InitializeComponent method of the form when I drop the control in a form, making it impossible to later change the value for all instances (controls) by just changing it in the contructor of the subclass. Is there some ...Show All

• Software Development for Windows Vista Get MPEG2Demultiplexer PID Info in C#

  This is my first post here so I hope i'm doing everything correctly. I have a BDA DVB-t app that i'm working on. i am adding a second MPEG2Demultiplexer via an InfTee. I add a Multiplexer and a dump filter to be able to record. I have created the Video and Audio pins and am able to use MAPPID for the pins. I have looked everywhere for information on how to get the current Video and Audio PID info from the first MPEG2Demultiplexer so as to map the second but have only found C++ info. they use QueryInterface i believe but i'm not sure what the equivelant is in C#. or is there another way in C#. I have also used the PSIParser filter connected to a third MPEG2Demultiplexer without success. Any help would be great. i hope this ...Show All
